Abstract

La présente invention concerne un procédé d'induction de cellules souches pluripotentes personnalisées, des cellules souches pluripotentes préparées au moyen du procédé et une composition contenant les cellules souches pluripotentes. Les cellules souches pluripotentes personnalisées sont induites par une reprogrammation de cellules différenciées adultes à l'aide d'acide shikimique, d'un extrait végétal contenant de l'acide shikimique, ou d'un extrait de cellules souches végétales et de cellules souches végétales redifférenciées (callus). Selon la présente invention, étant donné qu'un ovule n'est pas utilisé pour préparer des cellules souches pluripotentes ayant les mêmes aptitudes que les cellules souches embryonnaires, les problèmes d'éthique peuvent être résolus. Mais avant tout, par l'utilisation d'un extrait de cellules souches végétales qui s'est révélé inoffensif pour l'homme, des cellules souches pluripotentes présentant une sécurité garantie peuvent être préparées. Aussi, la présente invention peut être utilisée pour mettre au point un agent thérapeutique cellulaire immunocompatible, personnalisé pour chaque sujet. En outre, on prévoit que la présente invention puisse être très utile dans l'étude d'une méthode thérapeutique et l'identification de la cause d'une maladie par l'induction de cellules souches pluripotentes issues d'un sujet atteint de la maladie. La présente invention concerne également une composition contenant de l'acide shikimique ou un extrait végétal contenant de l'acide shikimique.
